I don't really think its internalized homophobia. In fact, Taehwan never even said the word "gay" in a negative connotation (I think). I think its more the fact that Yeonwoo kissed him while he was sleeping in high school and climbed on top of him in college. That's sexual assault. THAT'S what's disgusting. Him showing his true nature. This is where the stereotypes come into play because people think "bottoms" are weak and fickle, so them being assaulters isn't something that would happen. But no one wants to have that conversation. Taehwan befriended a person just to get take advantage of. Trust me, I love Yeonwoo more than anyone but this "internalized homophobia" shit is getting on my nerves because Yeonwoo isn't the victim, Taehwan is. And now he's getting seen as homophobic just because he's frustrated.
